lu ix. (TnfoUum repens) a uniformly maximum degree was noted. 
In X. {Plantago) the general vigour was liigli, with but slight 
fluctuation. 
In xi. (AcJiiUea) a high degree (e,f) was maintained till after 
the cutting, when in October the degree was low (b). 
In xii. (Carum) the degree of vigour was uniformly high (e). 
In general terms the mineral and ammonia-salts combined seem 
to have exerted a favourable influence on the grasses up to the 
time of cutting, but the plants declined in vigour afterwards. In 
the white clovers the degree was uniformly high ; but in the T. 
pratense there was a decline in October ; in the plantain, vigour 
high throughout ; in Achillea, high till the time of cuttiug, th.e 
second growth low ; in Carum, both before and after cutting, high. 
JBox 6. Mineral and Nitrate. 
i. {Dactylis). Much fluctuation ; beginning high, subsequently 
declining. 
ii. {AntJioxantlmm') . Maximum throughout till the cutting, sub- 
sequently declining. 
iii. (LoUutn perenne). High throughout, without much fluctuation. 
iv. {Pod). Maximum throughout up to the time of cutting, sub- 
sequently declining. 
V. {JPoa trivialis). Medium at first, rising to maximum in July. 
vi. (Bromus). High throughout with but little fluctuation. 
vii. {Trifoliim pratense). Medium throughout to the time of 
cutting, subsequently attaining a maximum. 
viii. {Lotus corniculatus) . High throughout to the time of 
cutting, after which the plants declined to the minimum. 
ix. {Trifolium repens). Medium throughout. 
X. {Plantago) . High at first, declining to medium, rising slightly 
after the cutting. 
xi. {AcJiillea). High at first, declining to minimum after the 
cutting. 
xii. {Carim). Maximum without fluctuation throughout. 
The effect of mineral manures and nitrate combined, so far as 
can be gleaned from these experiments, was generally good in the 
case of the grasses ; but much fluctuation was manifest in the case 
of the Dactylis, and a tendency to arrest in the second growth in 
some of the grasses. In Trifolium pratense the vigour was mediiiin 
till after the cutting, when it rose to maximum. In Lotus the 
degree of vigour was high till the cutting, when it declined to
